Toward the Realization of Concrete Floating Structures for Offshore Wind Power Generation in Japan

Abstract

In this paper, an overview of the contents of the Design and Construction Guidelines for Concrete Floating Offshore Wind Power Facilities in Japan was provided. According to the guideline, a case study of a concrete floating structure supporting 10MW wind turbines was presented. The structural safety and durability were assessed based on stresses and strains obtained from nonlinear FE analysis even if the design load case applied in this study was limited. It is expected that further detailed examinations of concrete floating structures ultimately contribute to adoption and promotion of concrete floating structures in the world.
